LR5N-B Series Print
DIN W48×H24mm, Indication only, LCD Pulse Meter(RPM,RPS,Hz)
Compact LCD pulse indicator LR5N-B Series is upgraded version of LR7N Series. The series contributes to better user convenience by adopting 1 pulse input per rotation method and wide display range up to 10,000rpm. Moreover, built-in battery allows no power supply and wiring works. Rotator’s RPM and RPS display function in another feature of LR5N-N Series to increase user’s satisfaction.
